Saving digital photographs

Before the days of digital, the film was both the capture medium as well as the storage device for our precious photos. Now the two tasks are split. The sensor handles the capture part of the process and the camera's memory card is responsible for the storage (at least until it is transferred to your computer). There are several different types of cards and they also vary in capacity (how many photos they can store) and transfer speed. For readers with cameras with high resolution chips the faster the transfer speed of the card the quicker the pictures will be written to and read from the card. Memory card prices have fallen dramatically in the last couple of years so you should buy the largest capacity and fastest transfer speed that you can afford (see Figure 9.7).

Figure 9.7 Memory cards store the pictures captured by the digital sensors. Different manufacturers favor different card types. Check which type your camera uses before purchasing additional cards.

10 Films (see Figure 10.1)

Film records the image exposed onto it in your camera, using light-sensitive chemicals (silver halide crystals) coated as a gelatine emulsion on a plastic base. The size, shape and how tightly packed these silver halides are basically determines the speed of a film - from fine grained and relatively 'slow' in reaction to light, to coarser grained and 'fast' in sensitivity.
